The liquid feeding apparatus includes a main unit in which the press roller is provided, and a liquid cassette which accommodates a liquid cartridge. One end of the elastic tube is connected to a reservoir for the liquid to be fed, and the other end is connected to a check valve. The liquid cassette is removably fitted to the liquid feeding apparatus so that the elastic tube is subject to pressing action of the press roller.Field of SearchDeformation by rolling or sliding engagement memberPlural spaced engagement members or member portions Cassette Specific rollers or slides structure Specific backing member for flexible wall Deformable resilient chamber type For bottom discharge dispenser supported on horizontal surface Motor operated | |
